Product Information
Full details
This guide is for electrical engineers, panel builders, and maintenance technicians working with low-voltage control circuits. The Phoenix Contact 3270203 fuse modular terminal block offers a secure and efficient way to integrate fuse protection directly into DIN rail mounted systems, significantly simplifying circuit design and maintenance. A key benefit is its push-in connection, allowing for fast, tool-free wiring. However, users should note its specific voltage and current limitations (24V, 6.3A). This block features a compact, single-level design for 6mm² wire, accommodating 5x20mm fuse inserts and providing a defect indication voltage.

FAQs
What type of fuses can be used with the PTC 4-HESILED 24?
This terminal block is designed for 5x20mm fuse inserts, commonly known as G-type fuses, made of glass, ceramic, or similar materials.
Can I use stranded wire without ferrules?
Yes, fine-stranded conductors ranging from 0.2mm² to 4mm² can be connected without ferrules using the push-in connection.
What is the purpose of the defect indication feature?
The defect indication feature, powered by a 12-30V supply, typically uses an LED to signal when a fuse has blown, helping to quickly identify circuit faults.
Does this terminal block come with a closing plate?
No, a closing plate is required for installation but is sold separately. It is essential for ensuring proper insulation and mechanical stability at the end of a terminal block assembly.
What is the maximum voltage and current rating?
The nominal voltage is 24V, and the nominal current is 6.3A.
How do I install this on a DIN rail?
The terminal block can be snapped directly onto a standard 35mm DIN rail (NS 35/7.5 or NS 35/15).
What is the operating temperature range?
The terminal block can operate within an ambient temperature range of -60°C to 85°C.
Troubleshooting
Terminal block not making a secure connection
Ensure the conductor is stripped to the correct length and is of the appropriate type (solid, stranded with ferrule). Push the conductor firmly into the connection point until resistance is felt.
Fuse blows repeatedly
The circuit is experiencing an overcurrent condition. Investigate the connected equipment for faults or ensure the fuse rating (6.3A) is appropriate for the load.
Defect indication LED does not light up
Verify the supply voltage (12-30V) is correctly connected to the terminal block and that the voltage is within the specified range. Check the LED itself for damage.
Terminal block is loose on the DIN rail
Ensure the terminal block is fully seated on the rail. Check if end stops or closing plates are correctly installed to maintain tension.
Pros and Cons
Pros
- Tool-free wiring speeds up installation.
- Compact size saves valuable DIN rail space.
- Integrated fuse protection simplifies circuit design.
- Defect indication provides real-time status.
- Wide range of supported conductor sizes.
Cons
- Limited to low voltage (24V) and current (6.3A) applications.
- Requires a separate closing plate for complete assembly.

Setup, Compatibility & Care
Setup:
- Mounting: Snap the terminal block onto a standard 35mm DIN rail (NS 35/7.5 or NS 35/15).
- Wiring: Insert solid conductors (0.2mm² to 6mm²) or fine-stranded conductors with ferrules (0.2mm² to 4mm²) directly into the push-in connection terminals. For fine-stranded conductors without ferrules, use sizes from 0.2mm² to 4mm².
- Fuse Insertion: Open the swivel-out fuse holder and insert a 5x20mm fuse. Close the holder securely.
- Closing Plate: Install a closing plate (sold separately) at the end of the terminal block row for insulation and mechanical stability.
- Defect Indication: Connect the supply voltage (12-30V) to the appropriate terminals if the defect indication feature is to be utilized.
Compatibility:
- DIN Rail: Compatible with standard 35mm DIN mounting rails.
- Wire Size: Accepts solid and fine-stranded conductors from 0.2mm² to 6mm² (AWG 24-10).
- Fuse Size: Specifically designed for 5x20mm G-type fuse inserts.
- System Integration: Part of the CLIPLINE complete system, ensuring compatibility with other Phoenix Contact terminal blocks and accessories.
Care:
- Cleaning: Use a dry, lint-free cloth to clean the exterior. Avoid using solvents or abrasive cleaners.
- Inspection: Periodically inspect connections for tightness and the fuse for continuity. Ensure the housing is free from damage.
